While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

Pavers are a type of permeable hardscape that can be used for driveways, patios, walkways, and other landscaping features. Unlike poured concrete or asphalt, pavers typically have a layer of gravel underneath to prevent water runoff from damaging your property—though you can also lay pavers on grass. Because pavers are installed piece by piece, you can customize a one-of-a-kind hardscape that best suits your aesthetics, boosting your curb appeal along the way.

Driveway pavers are often worth the cost. Paver types like cobblestone, brick, and concrete are highly durable, and permeable paver options can be tremendously eco-friendly. While you may pay more for a paver driveway, you’ll see great returns from the increased curb appeal and low maintenance compared to other types of driveways.
